Consider the traffic flow diagram that follows, where a1, a2, a3, a4, b1, b2, b3, b4 are fixed posi-
tive integers. Set up a linear system in the unknowns x1, x2, x3, x4 and show that the system
will be consistent if and only if
a1 + a2 + az + a4 = b1 + b2 + b3 + b4
What can you conclude about the number of automobiles entering and leaving the traffic
network?
